Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105624, here are decompositions:
- 5 + 105619 = 105624
- 11 + 105613 = 105624
- 17 + 105607 = 105624
- 23 + 105601 = 105624
- 61 + 105563 = 105624
- 67 + 105557 = 105624
- 83 + 105541 = 105624
- 97 + 105527 = 105624
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 624 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
